Abstract (en)

[origin: US2022404618A1] A display system is disclosed including an emitter system assembly for providing a light output. The emitter system assembly includes a first emitter that provides a first emission spectrum, a cavity at least partially surrounding the first emitter, a first aperture configured for transmitting therethrough at least a portion of the first emission spectrum from the first emitter, and a shaping element in optical communication with the first aperture. The cavity includes reflectors that reflect the first emission spectrum within the cavity and toward the aperture.
